11. Fabrication of nanocellulose-based materials : Liquid crystalline phase formation and design of inorganic–nanocellulose hybrids
Sammanfattning : The increasing need to replace fossil fuels as a source of energy and raw material is resulting in extensive research efforts towards identifying and developing high performance materials and devices based on renewable sources. Cellulose being the most versatile and abundant biopolymer in nature is one of the obvious choices. LÄS MER
12. Closed-loop strategy for valorization of starch : From starch to functionalized starch biomaterials and bioplastics
Sammanfattning : The desire to utilize renewable resources and avoid wastes drives us to develop new concepts for material design. Non-edible starch feedstocks and starch bioplastic wastes were previously considered useless. LÄS MER
13. On the multifunctional performance of structural batteries
Sammanfattning : The structural battery composite is a composite material that can store electrical energy (i.e. work as a battery) while simultaneously provide mechanical integrity in a structural system. Due to its inherent ability to store energy this material offers significant weight savings on a system level. LÄS MER
14. Environment-Sensitive Multifunctional Drug Delivery Systems
Sammanfattning : Drug delivery systems (DDS) with multiple functionalities such as environment-sensitive drug release mechanisms and visualization agents have motivated the biomedical community as well as materials chemists for more than a decade. This dissertation is concerned with the development of nanoparticles for multifunctional DDS to tackle several crucial challenges in these complex systems, including polymeric nanospheres which respond to temperature change, superparamagnetic iron oxide nanoparticles/polymeric composite for magnetic resonance imaging contrast agents and drug carriers, immunoresponse of nanomaterials and injectable magnetic field sensitive ferrogels.

15. Nanoparticles for multifunctional drug delivery systems
Sammanfattning : Multifunctional drug delivery systems incorporated with stimuli-sensitive drug release, magnetic nanoparticles and magnetic resonance (MR) T2 contrast agents is attracting increasing attention recently. In this thesis, works on polymer nanospheres response to temperature change, superparamagnetic iron oxide nanoparticles (SPION)/polymeric composite materials for MR imaging contrast agents are summarized.
